I flashed my DS phat because having the superkey in the DS slot was draining the battery really quick and I didn't want to be charging it every other day. Since I have flashed it the battery life is much better.

The problem is that now it's flashed I have lost the 'close the lid to pause' function. I have read that if I put a 'real' game, or a dummy card in the DS slot then this function will work again, but does it have the same effect on the battery life that having the superkey in there does?

There are two pins in slot 1 that have to be connected to each other for sleep mode to work. A standard DS game will do this, but it will also consume some battery power. Ewin makes a dummy cart designed specifically for enabling sleep mode without draining the battery, but I don't know where to buy one.
